Huntsville Unit


The Huntsville Unit, also known as the Walls Unit, is a significant landmark in Texas state prisons. Established as the first prison in Texas, it earned its moniker from the imposing 15-foot brick wall encircling the prison yard. This formidable structure has become an emblem of the institution’s storied past and enduring legacy.

Dating back to 1849, the Walls Unit holds the distinction of being the oldest prison in Texas. Over the years, it has witnessed numerous pivotal moments in the state’s penal history, shaping its identity as a correctional facility with a rich heritage. Notably, the prison experienced a harrowing event during the summer of 1974 when three inmates staged a siege armed with contraband firearms, sparking a tense standoff that captured national attention.

Despite its historical weight, the Huntsville Unit continues to operate within the Texas Department of Criminal Justice framework, upholding its incarceration and rehabilitation mission. The facility plays a crucial role in the state’s correctional system, serving as a focal point for inmate placement, release, and transitional programs to facilitate successful reentry into society.
